Infant jaundice is a common condition affecting many newborns. It occurs when a baby’s blood contains an excess of bilirubin, a yellow pigment of red blood cells. Typically, jaundice is visible in the first few days after birth, presenting as a yellow tint in the skin and the whites of the eyes. Understanding its causes, symptoms, and treatments is essential for ensuring the well-being of newborns.
Causes of Infant Jaundice
Physiological Jaundice
Most newborns experience physiological jaundice. This type of jaundice occurs because a newborn’s liver is not yet fully developed and cannot efficiently process bilirubin. As the liver matures, it becomes more effective at filtering out bilirubin, and jaundice typically resolves without intervention.
Breastfeeding Jaundice
Breastfeeding jaundice is seen in some breastfed babies in the first week of life. It is often due to insufficient intake of breast milk, leading to dehydration or low caloric intake, which can exacerbate jaundice. Ensuring proper breastfeeding techniques and frequent feeding can help mitigate this form of jaundice.
Breast Milk Jaundice
Breast milk jaundice can appear in healthy, breastfed babies after the first week of life, peaking around the second or third week. It is thought to be caused by substances in the mother’s milk that promote increased bilirubin levels. Although this type of jaundice can persist for a longer period, it usually does not cause harm and tends to resolve on its own.
Hemolytic Jaundice
Hemolytic jaundice occurs when there is an increased breakdown of red blood cells, leading to higher levels of bilirubin.
Conditions such as Rh or ABO incompatibility, where the mother’s blood type conflicts with the baby’s, can cause this rapid breakdown. Babies with hemolytic jaundice often require more intensive treatment.

Other Causes
Other causes of infant jaundice can include infections, enzyme deficiencies, or other metabolic disorders. These conditions are less common but require medical attention for appropriate management.
Symptoms of Infant Jaundice
The primary symptom of jaundice is yellowing of the skin and eyes. This yellow tint usually starts on the face and moves down the body. In severe cases, the baby may also show signs of:
Poor feeding or lethargy
Dark urine (instead of the usual light-colored urine in newborns)
Pale-colored stools (normally yellow or orange in breastfed babies)
Diagnosing Infant Jaundice
Physical Examination
A healthcare provider will typically start with a physical examination, noting the extent of yellowing on the skin and eyes. The doctor might also press gently on the baby’s forehead or nose to check for yellow discoloration.
Bilirubin Levels
If jaundice is suspected, the next step is to measure the bilirubin levels in the baby’s blood. This can be done using a non-invasive transcutaneous bilirubinometer or through a blood test. The results help determine the severity of jaundice and the necessary treatment.
Additional Tests
In cases where the jaundice is severe or the cause is unclear, further tests may be needed. These can include:
Blood type tests to check for blood group incompatibility
A complete blood count (CBC) to assess overall health and detect hemolytic anemia
Tests for infections or other underlying conditions
Treatment Options for Infant Jaundice
Phototherapy
Phototherapy is the most common treatment for significant jaundice. It uses blue light to break down bilirubin in the baby’s skin, making it easier for the liver to process and excrete. The baby is placed under a special light, and their eyes are protected to prevent damage. Phototherapy can be done in a hospital or at home with the right equipment.
Exchange Transfusion
In severe cases of jaundice, an exchange transfusion may be necessary. This procedure involves slowly removing the baby’s blood and replacing it with donor blood. Exchange transfusion rapidly reduces bilirubin levels and treats severe anemia.
This is usually performed in a neonatal intensive care unit (NICU).
Intravenous Immunoglobulin (IVIg)
For babies with hemolytic jaundice due to blood type incompatibility, intravenous immunoglobulin (IVIg) can be administered. IVIg reduces the need for exchange transfusion by lowering bilirubin levels more rapidly. It works by reducing the breakdown of red blood cells.
Supplemental Feeding
For breastfeeding jaundice, increasing the frequency of feedings can help reduce bilirubin levels. Sometimes, supplementing with formula may be necessary to ensure the baby is getting enough fluids and calories. Working with a lactation consultant can be beneficial in managing breastfeeding techniques.
Home Care and Monitoring
Frequent Feeding
Ensuring the baby feeds frequently can help promote regular bowel movements, which aids in the excretion of bilirubin.
Breastfed babies should be fed 8-12 times a day, and formula-fed babies should also have regular, frequent feedings.
Sunlight Exposure
Brief, indirect sunlight exposure can help reduce bilirubin levels. Place the baby near a sunny window for short periods, but avoid direct sunlight to prevent skin damage.
Monitoring
Parents should regularly monitor their baby’s skin color, feeding patterns, and behavior. Keeping track of the baby’s jaundice symptoms and consulting with healthcare providers as needed is crucial for managing the condition effectively.
Prevention of Infant Jaundice
Prenatal Care
Good prenatal care can help prevent some causes of jaundice. Blood type and Rh factor screening during pregnancy can identify potential incompatibility issues. If an Rh incompatibility is detected, the mother can receive Rh immunoglobulin to prevent complications.
Early Feeding
Encouraging early and frequent breastfeeding can help reduce the risk of jaundice. Early feeding stimulates the baby’s digestive system and promotes regular bowel movements, aiding in bilirubin excretion.
Monitoring High-Risk Babies
Babies born prematurely, with low birth weight, or with a family history of jaundice should be closely monitored. These infants are at higher risk and may require additional follow-up and early intervention.
When to Seek Medical Attention
While jaundice is common and usually harmless, certain signs indicate the need for immediate medical attention. These include:
Jaundice appearing within the first 24 hours after birth
Rapidly increasing yellow discoloration
High-pitched crying or excessive lethargy
Poor feeding or refusal to feed
Dark urine or pale stools
Long-Term Outlook and Complications
Kernicterus
If severe jaundice is left untreated, it can lead to a condition called kernicterus, a form of brain damage caused by very high levels of bilirubin. Kernicterus can result in permanent neurological damage, including hearing loss, vision problems, and developmental delays. Prompt treatment of jaundice is crucial to prevent this complication.
Developmental Monitoring
Babies who had severe jaundice or required intensive treatment should have regular developmental check-ups. Early intervention programs can help address any delays or disabilities resulting from jaundice complications.
Conclusion
Infant jaundice, while common, requires careful monitoring and sometimes medical intervention to ensure it resolves without complications. Understanding the causes, recognizing symptoms, and knowing when to seek medical help are crucial steps for parents and caregivers. With proper care and timely treatment, most babies recover fully from jaundice and go on to thrive.
